On Rudis suggestion im posting this here with hopes of resolving this problem.I have a 3160 deck on my 154,I have rebuilt all 3 spindles,new blades and belts,deck is level.I have problems with it scalping in certain areas in my yards and it leaves a trail of grass in the same are that the outside left blade rides,as if sitting on it.It does throw some out the side,but not all of it.I have switched blades around and still have the same problem there,new gauge wheel and assembly on each side,and new skids.Tires are are proper level and on same level surface as I chekced it deck,it sits level.I have changed,replaced,leveled,tightened lossened and cussed til my head exploded .Any ideas as to what it going on,do they make "high lift" blades for these things? Thanks!~

All three blades are cutting right,its just that under the left blade it leaves a trail of cut grass.Its not a big deal when I keep the yard cut down besause it isnt that bad,but having to cut this three acre lot with a house in the middle evry Sat is taking time away from the shows,and I hate missing the shows!Someone had sent me an email suggesting that maybe the deck was indeed like both of you said and level front to back as well,which I think it was.Ill set it right and see what happens next week if it gets up hiogh enough by then,thank goodness its getting cool now!
